MACHINE FOR TE NOI\ IING AND BORING IMPLEMENT-HANDLES.

SPECIFICATION forming part of Letters Patent No. '7' 55,359, dated March22, 1904;.

Application filed October 14, 1903.

To all whobt it may concern.-

Be it known that I, GEORGE S. OLow, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Machines for Tenoningand Boring Implement-Handles; and I do hereby declare the following tobe a full, clear, and eXact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

The object generally of this invention is to' provide an improvedmachine for simultaneously tenoning and boring an implement-handle,whereby time and labor are saved.

Special objects, among others, are to provide an automatically-operativegage or stop and an automatically-operative chuck or holder for thehandle while being tenoned and bored, so that the only manual operationsrequired are the insertion into and removal from the chuck of the sticksconstituting the handles, and means whereby the tenoning andboringtool-is made self-clearing.

The invention consists in the combinations of parts hereinafterdescribed and claimed.

In the accompanying drawings, illustrating one embodiment of theinvention, Figure 1 is an elevation taken at the left-hand side of themachine as faced by the attendant. Fig. 2 is a top plan view. Fig. 8 isa section on the line so a", Fig. 2. Fig. 4 is a front view of the chuckand operating devices with the front covering-plate removed. Fig. '5 isa diametrical section of the chuck. Fig. 6 is a detail of the tenoningdevice or shaper. Fig. 7 is a section of the same on-line 3/ Fig. 6.Fig. 8 is a detail of the stop or gage and its operating devices.

1 designates a bed that is supported upon legs 1. The bed supports aslide or carriage 2, having separated bearing-containing parts 2 risingtherefrom that in turn support a rotatable mandrel or shaft 3, having abelt-pulley 3 between the bearingcontaining parts 2 for the applicationof the necessary power to turn the mandrel. This mandrel 3 has anenlarged forward end 3*, into which is screwed the threaded shank of thetool-holder 4:. The toolholder L contains an appropriate knife or SerialNo. 177,050. (No model.)

knives 4 for tenoning or shaping the outer side or ferrule-receivingportion of the stick and a bit 4 located in the axis of the toolholder.The bit 4" is preferably removable from the tool-holder and is locked inplace after the holder has been screwed up into place by means of aset-screw 3, passed through the end 3 and ahole in the threaded shank ofthe tool-holder and having its end pinching the bit. The set-screw alsoprevents the toolholder from turning in its seat. The rear end of themandrel turns against a brass bearing 3, seated in a box 3" to take thethrust of the mandrel when working, said brass bearing being supportedby one or more adjustable setscrews 3 to compensate for wear.

Journaled on an appropriate bracket 5 at the rear end of the bed is ashaft 5, standing at right angles to the mandrel 3. The shaft 5 carriesat its left-hand end opposite the rear end of the mandrel 3 a groove-cam5 the groove of which engages a stud 23, secured to and projecting fromthe rear end of the toolcarriage 2. The groove of the cam is of suchform, substantially as shown, that it moves the tool-carriage forwardand backward twice in one revolution of the cam. The backward movementbetween the two forward movementsis for the purpose of allowing the toolto clear itself of shavings and chips.

Journaled in brackets 6 at the right-hand side of the bed is a shaft 6,standing parallel to the mandrel 3. This shaft contains a belt-pulley6", and power is transmitted from this shaft to the shaft 5 by means ofa miter-gear 6 on the rear end of the shaft 6, meshing with a similargear 5" on the shaft 5.

Secured to the front end of the bed. is the chuck for holding the stickconstituting the handle when it is tenoned and bored. This chuckcomprises a frame-plate '7, several radially-arranged sliding shanks 7 Ihaving clamping-jaws 7 and pins 7 and adisk 7 having eccentric slots 7engaging the pins 7 so that when the disk 7 is turned the jaws 7 aremoved inward or outward, according to the direction in which the disk isturned. At-

tached to the disk 7 and extending laterally therefrom and above theshaft 6 is a lever-arm 7 having a downward projection 7 prefer- IOQ ablyprovided with an antifrictionroller 7 The opening between theclamping-jaws 7 is 7 arm 7 and separate the clamping-jaws? to permit ahandle that is to be tenoned and bored to be inserted and the removal ofthe handle after it has been so treated, and the lever-arm 7 can beweighted or provided with a spring 7 attached to a fixed part of themachine to hold the jaws closed on the handle to secure or chuck ittightly while being tenoned and bored.

The gage or stop for determining the distance the handle to be treatedshall be inserted into the chuck consists of a lever 8, fulcrumed onsmall standards 8 adjustable and fixable on the bed 1, so that the innerend of the lever can stand across the path of the toolholder at thedesired distance from the chuck.

The outer end of the lever 8, whichis pro-.'

vided with an antifriction-roller 8, extends over the shaft 6, whichlatter is provided with a cam 6 shaped to depress and hold the inner endof the lever out of the way when the tenoning and boring operation takesplace and permit that end to rise. when it is to serve as a stop orgage, the lever being of sufficient weight at its outer end or weightedor provided with a spring for that purpose.

Inoperation the power-shaft 6 and mandrel are driven with a constantmotion. The workman inserts the end of a stick that is to constitute thehandle of the fork, rake, hoe, or other implement into the chuck,whenthe jaws thereof are separated, the gage limiting the extent to whichthe stick is insertible. The jaws of the chuck then close tightly on thestick, and the gage automatically moves down out of the way. After thisthe tenoning and boring tool moves up onto the end of the stick andshapes it externally for the usual ferrule and bores it internally forthe shank of the implement; but by reason of the shape of the groove-cam5 at the rear of the machine the cutting and boring tool makes twoforward and two rearward movements, the first rearward movement beingsufficient to permit the toolholder to clear itself of shavings andchips, and therefore to do clean perfect work. The rapid motion andflaring shape of the opening of the tool-holder effects thisautomatically through centrifugal force on the shavings and chips. Thusit will be observed that both the tenoning and boring of the handle areeffected simultaneously and that all the operations except the mereinsertion and removal of the handles from the chuck are performedautomatically.

What I claim, and desire to secure by Letters Patent, is

1. In a machine for tenoning and boring implement-handles, thecombination of-a tool for simultaneously tenoning and boring thehandle-blank, a reciprocating carriage for supporting thetool, meansforrotating the tool, and means for automatically gaging and chucking orholding the handle-blank while the ten oning and boring tool is movedonto it.
